MACHINE FOR CUTTING AND CRIMPING PIPES.

To all whom it may concern:

Be it known that we, THEODORE A. JANs- SEN and HARRY W. MoA'rs, citizensof the United States, residing at Sterling, in the county of Whitesideand State of Illinois, have invented certain new and useful Improvementsin Machines for Cutting and Crimping Pipe and we do declare the following to a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse 'the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which form a partof this specification.

Our invention has reference to machines for cutting and crimping pipe,and is specially designed to be used in operating upon pipes formed oflight material, such as stovep I3y the use of the device it is possibleto cut the pipe at a pre-determined point and crimp the opposite endthereof in thesame operation, the pipe being held and fed in the machineso as to insure a perfectly true cut, at right angles to the line of themachine. It is also possible, by a slight adjustment to cause the pipeto be out only, the crimping mechanism being rendered inoperative.

In the drawings: Figure 1 is a side elevation of our invention. Fig. 2is an enlarged detail, with the plate 53 in position. Fig. 3 is adetail, showing the collars 36 and 37 in side view. Fig. 4 is a rearview of the plate 43 and appurtenant parts, with some of-the parts incross-section. Fig. 5 shows one of the blocks 54, in detail. Fig. 6 is avertical cross-section, in the line w0c of Fig. 1.

Similar numbers refer to corresponding parts throughout the severalfigures.

1 represents a support, adapted to be fastened to a bench or othersuitable place, by means of a clamp-foot 2 and bolt 3 therein. Astandard 4 is revolubly mounted in the support 1 by means of acylindrical shaped shank 5 on the lower end of such standard, engaging asimilar recess 6 in the support. Such standard may be held from rotationby means of a set-screw 7 held in the wall of the support 1 andimpinging the shank 5 with its inner end. Greater stability of the part4 upon the support 1, and greater ease of operation thereof, is securedby means of a circular plate or collar 8 on the lower end of theSpecification of Letters Patent.

standard 4, and a similar plate 9 on the upper end of the support uponwhich said firstnamed plate rests.

Integral with the standard 4 is an arm 10, provided on its outer endwith a bearing 11, the standard 4 being also projected upwardly into aplate 12, integral with the upper part of which is an arm 13, parallelwith the arm 10, and in vertical alinement therewith. On its outer endthe arm 13 is provided with a head 14.

A rotary shaft 15 is journaled near its outer end in the bearing 11, andnear its inner end in the plate 12, the inner end thereof being providedwith a crank 16. A similar shaft 17, parallel with the shaft 15, issupported near its outer end in the head 14, and at its inner end in theplate 12, rotation being imparted to the shaft 17 from the shaft 15 bymeans of a gear wheel 18 fixed on the latter shaft and meshing with asimilar wheel 19 on the shaft 17.

The outer end of the shaft 17 is capable of vertical movement by beingsupported in a block 20 having vertical play in a recess 21 in the head14. The block 20 can be raised or lowered by means of a screw 22 workingin a threaded perforation 23 in the head 14, the lower end of the screw22 being provided with a circular plate 24 held in a recess 25 in theupper face of the block 20 by means of a plate 26, secured to the faceof the block, and through which the lower end of the screw passes. Theupper end of the screw 22 is provided with a crank 27 by means of whichit is operated.

The inner end of the shaft 17 is permitted a limited amount of verticalflexibility by means of a recess 28 in the upper part of the plate 12,in the lower end of which recess is a journal-block 29 bearing upon theupper face of the shaft. In the upper end of the recess is a bolt 30,between which and the block 29 is an eXtensile coiled spring 31.

On the outer end of the shaft 15 is a feedroll 32, integral with whichis a rotary cutter 33, and on the outer end of the shaft 17 is a similarfeed-roll 34, enga ing the feed-roll 32. Integral with the feed-roll 34is a rotary cutter 35, adapted to work with the cutter 33 in cutting thepipe.

A pair of collars 36 and 37 are slidably mounted on the shafts 17 and15, respectively, by means of ribs or feathers 38 on the inner faces ofthe collars, engaged by longi tudinal channels 39 in the shafts. Thecollars are held in vertical alinement by means of annular grooves 40therein, engaged by a pair of plates 41 secured to a plate 42. The plate42 is permitted vertical movement independently of the shaft 15 by meansof a recess 43 in the lower end of such plate, and by means of anopening 44 in the upper part of the plate 42 the shaft 17 is permitted alimited amount of vertical play independently of such plate.

At one side the plate 42 is provided with a perforated ear 45, in whichis held a set-bolt 46, and at the opposite side said plate is pro- Videdwith a perforated ear 47 in which is held a thumb-screw 48. The bolt 46and screw 48 are adapted to impinge the sides of the arm 10 with theirinner ends, and hold the plate 42 rigidly attached thereto. Fixed to thecollar 36 is a crimping-roll 49, and a corresponding crimping-roll 50 issecured to the collar 37. Integral with the rolls 49 and 50 are feedrolls 51 and 52, similar to the feed-rolls 32 and 34. A plate 53 can beattached to the outer face of the plate 42 by means of a thumb-screw 54held in perforations in such plates. The plate 53 is held from movementupon the screw 54 as a pivotal point by means of arms 55 bearing uponthe edge of the plate 42. The plate 53 is of the same thickness as thecrimping rolls, and when in position prevents the'insertion of the endof the pipe beyond the inner edge of the feed-rolls 51 and 52, andprevents the crimping of the end of the pipe. The plate 42 may beprovided with a similar plate 53 on the opposite side of the machine, ifdesired. On one of the faces of the arm 13 is a gage 56, indicating infeet and fractions of a foot the distance from the cutting point of thewheels 33 and 35.

- To operate the machine the thumb-screw 48 is loosened, permitting theplate 42 to be moved longitudinally of the shafts 15 and 17, such platecarrying with. it the collars 36 and 37 and crimping and feed rollsattached thereto, The plate 42 is again secured in place at the pointwhich will give the desired length to the pi e to be severed, byre-setting the screw 48. f it is intended to crimp the end of the pipethe plate 42 is set so that the outer face thereof is on a line with themark on the gage 56 which indicates the desired length of out. If it isintended to cut the pipe, without crimping the end thereof, the plate 42is set so that the line between the crimping wheel 49 and feed-roll 51is opposite the desired mark on the scale. It will be obvious that withthe plate 53 attached to the plate 42 the inner end of the pipe willextend to the inner edge of the feed-rolls 51 and 52.

With the plate 42 located in the proper position, the crank 27 isoperated to raise the shaft 17, separating the feed-rolls 32 and 34, andalso the cutters 33 and 35, sufficiently to permit the insertion of thepipe. The same operation opens the feed-rolls 51 and 52 and crimpingwheels sufficiently to permit the engagement of the end of the pipethereby. The pipe is then inserted, and the crank 27 operated to lowerthe shaft 17, causing the pipe to be engaged by both pair of feed rolls,by the cutter-wheels, and by the crimping wheels, if such wheelsarebeing used. By the operation of the crank'16 the shafts 15 and 17 arethen rotated toward each other, resulting in the cutting of the pipe.

As the feed-rolls 51 and 52 are similar to the rolls 32 and 34, androtate coincidently therewith, the pipe which is being cut is rotatedwith the same degree of speed at the inner end thereof, as at the pointwhere the cutting is performed, resulting in an even circular cut, atright angles to the line of the p1 e.

.lt is necessary to have the arms 10 and 13 of sufficient weight andstrength to prevent the cutter-wheels from springing apart during thecutting operation.

The amount of flexibility of the shaft 17 at its inner end may be variedby raising or lowering the bolt 30, whereby the tension of the spring 31is correspondingly diminished or increased.
